چکیده
Photocrosslinking of polymers for industrial applications show undoubted advantages related to the mild conditions needed and economical equipment. However, some issues include: use (i) mercury lamps as light sources, which poses concerns about safety energy consumption, (ii) typical additives, such halogen-free flame-retardant fillers (HFFR) are powdered materials, can scatter UV photons avoid a deep penetration light. In this study, we explore UV-curing an innovative EVA-POE blend containing hydrotalcite aluminum hydroxide HFFR in presence 370-nm LED, namely Ekopren® XI1321, plastic used coverage electric cables. Two commercially available photoinitiators (benzophenone ethyl Michler's ketone) were analyzed well two crosslinking coagents widely industry, that is, triallyl cyanurate trimethylolpropane trimethacrylate. A comparison with pure EVA LDPE was performed higher cross-linked content proposed blend, even scattering mineral at high concentration.

Organophosphorus Flame Retardants (OPFR): Neurotoxicity
Organophosphorus flame retardants (OPFRs) are used as additives in plasticizers, foams, hydraulic fluids, anti-foam agents, and coatings for electronic components/devices to inhibit flames. These chemicals were developed and used as flame retardants because of environmental and health concerns of previously used brominated and chlorinated flame retardants (FRs). OPCFRs are divided into five mai...
